View operating system details

---

This document describes how to set up and use OS inventory management. For an overview of OS inventory management, see OS inventory management.

Use OS inventory management to collect and view operating system details for your virtual machine (VM) instances. These operating system details include information such as hostname, operating system, and kernel version. You can also get information about installed OS packages, available OS package updates, and OS vulnerabilities. For a list of common scenarios for using OS inventory management, review When to use OS inventory management.

Before you begin

• If you want to use the command-line examples in this guide, do the following:
  1. Install or update to the latest version of the Google Cloud CLI.
  2. Set a default region and zone.
• If you want to use the API examples in this guide, set up API access.
• Review OS Config quotas.

Supported operating systems

For the full list of operating systems and versions that support OS inventory management, see Operating system details.

Permissions

Owners of a Google Cloud project have full access to inventory data. For all other users, you need to grant permissions. You can grant one of the following granular roles:

• roles/osconfig.inventoryViewer: contains permissions to list and describe inventory data.
• roles/osconfig.vulnerabilityReportViewer: contains permissions to list and describe vulnerability report data.

Example command to set permissions

To grant a user access to view inventory data, use the following command:

gcloud projects add-iam-policy-binding PROJECT_ID \
    --member user:[e-mail] \
    --role roles/osconfig.inventoryViewer

Replace the following:

• PROJECT_ID: the project ID
• USER_ID: the user's Google Workspace username

Set up your VM

Before you can use OS inventory management, you need to configure your VMs to use the feature. To configure your VMs to use OS inventory management, set up VM Manager.

After setting up VM Manager on your VMs, you can then view OS inventory data and vulnerability reports.

View OS inventory data

• To view OS inventory data, use one of the following methods:

  • Use the gcloud CLI or API
  • Use Cloud Asset Inventory

View OS inventory data using the gcloud CLI or API

gcloud

1. To view a list of inventory data for VMs in a specific zone, run the os-config inventories list command.

   gcloud compute os-config inventories list \
      --location=ZONE \
      --view=VIEW
   

   Replace the following:

   • ZONE: the zone where the VM is located

   • VIEW: the type of output information that is required. The following view types are available:

     • basic: displays only OS information
     • full: displays information about both OS and packages

     If unspecified, the default is basic.

   Example (basic view)

   gcloud compute os-config inventories list \
      --location=us-central1-c
   

   The output is similar to the following:

   INSTANCE_ID          INSTANCE_NAME  OS                                         OSCONFIG_AGENT_VERSION       UPDATE_TIME

OS inventory management (earlier version)

If you are still using the earlier version of OS inventory management, expand the following section to review the instructions for the Google Cloud CLI.

OS inventory management (earlier version)

List VMs

To view the list of VMs that have OS inventory management set up, run the instances os-inventory list-instances command.

For example, to list all the VMs that have inventory data, run the following command:

gcloud compute instances os-inventory list-instances

The output is similar to the following:

  NAME                 ZONE          MACHINE_TYPE   PREEMPTIBLE  INTERNAL_IP  EXTERNAL_IP STATUS
  inventory-instance   us-east1-b    e2-standard-2               192.0.2.1    RUNNING
  instance-inventory1  us-west1-b    e2-standard-2               192.0.2.2    RUNNING
  instance-inventory2  asia-east2-b  e2-standard-2               192.0.2.3    RUNNING
  

You can also use filters to narrow down your results. For example, you can list all VMs that have OS inventory management set up and whose hostname matches the regex instance-* by running the following command:

gcloud compute instances os-inventory list-instances
      --inventory-filter="Hostname~instance-*"

The output is similar to the following:

  NAME                 ZONE         MACHINE_TYPE   PREEMPTIBLE  INTERNAL_IP  EXTERNAL_IP STATUS
